New Guinea Impatiens plant named ‘Doimmalaven’

ABSTRACT

A new and distinct cultivar of  Impatiens  plant named ‘Doimmalaven’ characterized by its upright, outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; freely and early flowering habit; relatively large purple to red purple-colored flowers with white-colored centers; and good garden performance.

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘DOIMMALAVEN’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri and hereinafter referred to by the name ‘Doimmalaven’.

The new Impatiens plant is a product of a planned breeding program conducted by the Inventors in Koka, Ethiopia and Rheinberg, Germany. The objective of the breeding program is to create new early and freely flowering New Guinea Impatiens plants with large attractive flowers and good garden performance.

The new Impatiens plant originated from a cross-pollination made by the Inventors in November, 2013 in Koka, Ethiopia of a proprietary selection of Impatiens hawkeri identified as code number NN-0474, not patented, as the female, or seed, parent with a proprietary selection of Impatiens hawkeri identified as code number NN11-003606-002, not patented, as the male, or pollen, parent. The new Impatiens plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Rheinberg, Germany in April, 2014.

Asexual reproduction of the new Impatiens plant by terminal vegetative cuttings in a controlled greenhouse environment in Rheinberg, Germany since June, 2014 has shown that the unique features of this new Impatiens plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Impatiens have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylight and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Doimmalaven’. These characteristics in combination distinguish ‘Doimmalaven’ as a new and distinct Impatiens plant:

-   -   1. Upright, outwardly spreading and mounding plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves.     -   5. Freely and early flowering habit.     -   6. Relatively large purple to red purple-colored flowers with         white-colored centers.     -   7. Good garden performance.

Plants of the new Impatiens can be compared to plants of the female parent selection. Plants of the new Impatiens differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         the female parent selection.     -   2. Plants of the new Impatiens have larger flowers than plants         of the female parent selection.

Plants of the new Impatiens can be compared to plants of the male parent selection. Plants of the new Impatiens differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Impatiens are more vigorous than plants of         the male parent selection.     -   2. Plants of the new Impatiens have larger flowers than plants         of the male parent selection.     -   3. Plants of the new Impatiens and the male parent selection         differ in flower color as plants of the male parent selection         have rose red and pinkish lavender bi-colored flowers.

Plants of the new Impatiens can be compared to plants of Impatiens hawkeri ‘Kialdan’, disclosed in U.S. Plant Pat. No. 14,029. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Kialdan’ in the following characteristics:

-   -   1. Plants of the new Impatiens have larger flowers than plants         of ‘Kialdan’.     -   2. Plants of the new Impatiens and ‘Kialdan’ differ in flower         color as plants of ‘Kialdan’ have light purple-colored flowers         with white-colored centers.

Plants of the new Impatiens can also be compared to plants of Impatiens hawkeri ‘Duemagwis’, disclosed in U.S. Plant Pat. No. 26,782. In side-by-side comparisons, plants of the new Impatiens differ primarily from plants of ‘Duemagwis’ in the following characteristics:

-   -   1. Plants of the new Impatiens have larger flowers than plants         of ‘Duemagwis’.     -   2. Plants of the new Impatiens and ‘Duemagwis’ differ in flower         color as plants of ‘Duemagwis’ have light red-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the winter in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under cultural practices typical of commercial New Guinea Impatiens production. During the production of the plants, day temperatures averaged 26° C., night temperatures averaged 18° C. and light levels ranged from 4,500 to 5,500 lux. Plants were 25 weeks old when the photographs and description were taken.
